Witryna13 lut 2024 · Let's say we have a thin wire of an unknown material, and we want to obtain its modulus of elasticity. Assuming we measure the cross-section sides, obtaining an area of A = 0.5 × 0.4 mm.Then we measure its length and get L₀ = 0.500 m.. Now, we apply a known force, F = 100 N for example, and measure, again, its length, resulting … WitrynaA nonlinear finite element model was developed to investigate the biomechanics of indentation, particularly the influence of friction and large deformation on the calculation of the effective Young's modulus from the cylindrical, flat-ended indentation test of …
